Step-by-step explanation:
<u>Step 1: Define equation</u>
4x - 5 = x - 1 + 3x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 4x - 5 = 4x - 1
- Subtract 4x on both sides: -5 ≠ -1
Here we see that -5 does not equal -1.
∴ This equation has no solutions.
Answer:
Step-by-step explanation:
For the problem, , use rules for simplifying cube roots. Under the operations of multiplication and division, if the roots have the same index (here it is 3) you can combine them.
You can multiply it out completely, however to simplify after you'll need to pull out perfect cubes. Factor 24 and 45 into any perfect cube factors which multiply to each number. If none are there, then prime factors will do. You can group factors together such as 3*3*3 which is 27 and a perfect cube.

Answer:
2730 ways.
Step-by-step explanation:
There are 3 positions to be filled by the 15 runners.
For 1st place, we can fill this position in 15 ways.
After filling 1st place remaining runners = 14
Number 2 place can be filled by remaining 14 runners.
So, the 2nd place can be filled by 14 ways.
Again, after filling 2nd place remaining runners are 13.
Therefore, 3rd place can be filled by 13 ways.
Total number of ways to fill all three places = 15 × 14 × 13
= 2730 ways
